They certainly did. Whether you'd recognize them in those things is a different question.

Of the seven actors who played the von Trapp children in the 1965 classic "The Sound of Music," three didn't go on to do anything else. Charmian Carr (who played Liesl von Trapp), Duane Chase (Kurt) and Debbie Turner (Marta) more or less gave up on acting shortly after "The Sound of Music" -- going out on top, so to speak (that's a mountain pun, by the way).

The other four have a huge list of guest spots among them, some on very popular shows, but they were mostly of the blink-and-you'll-miss-them variety. There are a few exceptions, though.

Heather Menzies, who played Louisa, may also be remembered for screaming her way through a couple of cult-classic B-movies: the "Jaws" rip-off "Piranha" (1978) and the hilariously named "Sssssss" (1973), about a mad scientist turning people into snakes. It's a step down in prestige from doing Oscar-winning musicals, but fame is fame.

Nicholas Hammond has never stopped hustling for roles, and just recently wrapped production on an indie comedy called "The BBQ." However, aside from playing Friedrich in "The Sound of Music," he's probably best remembered for playing the title role in the short-lived live-action "Amazing Spider-Man" series in the late '70s (well, he's remembered by those who actually remember that show -- Marvel Comics would probably prefer that you forget it).

Angela Cartwright, who played Brigitta von Trapp, was actually somewhat famous before doing "The Sound of Music." She played Linda, one of the three Williams children, in the last seven years of the classic sitcom "Make Room for Daddy," which ended in 1964. She did "The Sound of Music" in '65, and then went right back to family TV, as one of the Robinson clan in the sci-fi sitcom "Lost in Space."

Kym Karath (Gretl von Trapp) fits into neither category. She didn't do anything else notable, but not for lack of trying. She was doing bit parts from the '60s up to the early '80s, but never found a permanent spot anywhere. Her longest run was two episodes of "Dr. Kildare" in 1966.

Ultimately, though, they all suffered the same fate: not one was able to turn early fame into adult success in the film business, which is a pretty common phenomenon among child stars.
